The Power of Dreams and the Neanderthal in your Genes

A child sleeping (c) Alessandro Zangrilli

In this NewsFlash, we find out how we may soon be able to predict the Asian monsoon - one of the most important weather events in the world.  We explore why dreaming helps you to remember things and find out about the stresses and strains a tablet experiences after you've swallowed it!  Plus, the Neanderthal in your genes - new genetic evidence that our ancestors interbred with other hominids on at least two occasions.

  • 06:11 - Stretching the limits of stem cells

    Stem cells research is a really exciting area of science, and one we often cover on the show. Now new research published in the journal Nature reports an important step forward in our understanding of stem cells, and how we might be able to use them in the future.

  • 09:04 - The Neanderthal in your Genes

    A new genetic analysis of nearly 2,000 people from all over the globe suggests that our ancestors interbred with Neanderthals over at least two different periods. Professor Jeffrey Long, from the University of New Mexico, explains more...
